In the days after Woods was injured in a November 2009 car crash in his Florida neighborhood, rumors surfaced about an alleged affair between the golfer and Uchitel. She initially denied the relationship and has refused to publicly talk about it.

Before starting the detective training, Uchitel was a cast member of the current season of TV's "Celebrity Rehab with Dr. Drew."

Dr. Drew Pinsky told HLN's Joy Behar last month that he diagnosed Uchitel as a "love addict," an affliction in which a person "mistakes intensity for intimacy."
